Answer:

<h2>              TRUE</h2>

Step-by-step explanation:

3x + y = 9    and  y = -4x + 10

so:

3x + (-4x + 10) = 9

3x - 4x + 10 = 9

 - x = - 1

   x = 1

Likurg_2 [28]

Answer:

x=2y−47x

Step 1: Add 47x to both sides.

x+47x=−47x+2y+47x

48x=2y

Step 2: Divide both sides by 48.

Well  slope means <span>a surface of which one end or side is at a higher level than another; a rising or falling surface.</span> So pretty much its just saying he had 6 litters used 4 of those litters and  had a remainder of 2.  So you can say the slope means that he was decreasing in litters by using 2 litters every 1 hour. I don know really if it´s correct so, sooopppeeerrrr sorry. :( :) bye

Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.

1800 + 500 = 2300 calories consumed Tuesday.

2300 - 100 = 2200 calories Wednesday.

(2200 - 1800)/2 = 400/2 = 200 calories

Which point is part of the solution of the inequality y 2 12x – 11.
Papessa [141]

Answer:

Point (0,0)

Step-by-step explanation:

Given the inequality y > 12x – 11.

We will check which of the given options will be applied for the inequality

A) (1,0)

Substitute with x = 1 and y = 0

0 > 12*1 - 11

0 > 1   ⇒ Wrong

So, Point (1,0) is not part of the solution of the inequality.

B) (3,2)

Substitute with x = 3 and y = 2

2 > 12*3 - 11

0 > 25  ⇒ Wrong

So, Point (3,2) is not part of the solution of the inequality.

C) (1,1)

Substitute with x = 1 and y = 1

1 > 12*1 - 11

1 > 1   ⇒ Wrong

So, Point (1,1) is not part of the solution of the inequality.

D) (0,0)

Substitute with x = 1 and y = 0

0 > 12*0 - 11

0 > -11  ⇒ True

So, Point (0,0) is part of the solution of the inequality.

Also, see the attached figure which represents the given inequality

The shaded area represents the solution of the inequality, and we can note that point (0,0) is part of the solution of the inequality
